Why the Nate Higga?
I wanted to investigate the nucleonics of Flourine 18.. It is used in medical scans.
The shyt is HOT.. The half-life of Fluorine-18. It emits positrons... I am not sure what those are, degreed and everything.

O) with a short half-life (~110 mins). Its instability (fewer neutrons than stable F-19) drives decay, producing positrons that annihilate to create detectable gamma rays, making it ideal for medical imaging tracers like FDG, due to its favorable nuclear properties and versatile chemistry.
Nuclear Characteristics
- Composition: 9 protons, 9 neutrons (Mass Number 18).
- Decay Mode: Primarily

O).
- Half-Life: Approximately 109.8 minutes (just under 2 hours).
- Energy: Emits low-energy positrons (max 0.635 MeV), resulting in high-resolution PET images.
Production & Application
- Production: Artificially produced in cyclotrons, most commonly by bombarding Oxygen-18 enriched water with protons (the

reaction).
- Medical Use: The most common radionuclide in Positron Emission Tomography (PET) imaging.
- Tracers: Used to create radiopharmaceuticals like Fluorodeoxyglucose (

F-FDG) for cancer, brain, and heart imaging.
Radiochemistry
- Versatility: Its chemistry allows it to be introduced into biomolecules via nucleophilic or electrophilic substitution.
- Reactions: Common methods involve nucleophilic fluorination (SN2) using precursors with good leaving groups (like tosylates or halides).
